FOLDING BED.

Application filed January 29, 1912.

To all whom it may concern Be it known that l Yunnan l1. Mur- Pin', a citizen of the llnited States. and a resident of the city and county of San Francisco. State of California, hate invented rertain new and useful improvements in Folding lleds, of which the following is a specification.

The invention l'iltlttlfi to beds which are movable about a horizontal axis to either vertical or horizontal positions.

The object of the invention is to provide means for locking the bed in the horizontal position.

A further object of the invention is to provide 11 ans for relieving the sup iorting frame or structure from the weight of the bed when it is in the horizontal position.

Another object of the invention is to provide an inn iroved structure for ct-unlerbal muting the weight of the bed as it is moved from one position to the other.

Another object of the invention is to prd vide an improved means for controlling the head of the llttl as the bed is moved.

The. invention possesses other "advantm geous features, which, with the foregoing will be set forth in the following description, where I shall outline in tull that form of embodiment of the invention which 1 have Selected for illustration in the drawings accompanying and forming part of the present description. The novelty ot the invention will be included in the claims sueceedin; said description. From this it will be apparent that 1 do not restrict myself to the showing: made by such drawings and description as 1 may adopt many variations within the scope ot my invention as expressed in said claims.

Referring to the drawings; Figure l is a. \erliral section taken through he bed in the horizontal position, several of the parts thereof being lJl'Ulltl. away. Fig. .2 is a similar view of the bed in the vertical po sition. l 'igr. is a detail of one side of the bed at the head. showing the arrangmnent of the counterbaiancing springs and the supporting legs. Fig. 4 is a detail view. illustrating the position oi the. counterbalaneint springs when the bed frame is ex tended.

The bed of my invention is of that class, termed generally folding beds, which are pivoted or hinged to move about a horizon- Sgecificatlon of Letters Patent.

tal axi that the bed may he moved from a vertical 5 sition to a horizontal position. and \ice vetsa. The bed frame 2 is provided on opposite sides with lugs 55. on each of which is formed a cylindrical boss or stub axle "l which bears in the link 5. lhe. link 5 pivotally attached to the bracket 6 which is secured to the wall or other structure from which the bed is supported. in Figs. 1 and 2 l have shown the i'rnnieti secured 116a carrving frame 7 which is hinged to the vertical sid-- ing 8, of an opening in the wall so that when the bed is in the vertical position it ma swine through the opening. The ear rjvin g frame T is particularly adapted to he used when the bed to he used 'n a bed of the disa pearing type and mav be formed integral with the supporting brackets t'. or the brackets may be atiached the i'to. lu-n the bed is se iiurr-d directly to a wall or other permanent -tltl llllt. the earl-ring frame 7 may be dispensed with and the brackets l1 attached directlv to the all or structure. It is preferable. however. to Ullll)l l a structure similar to that shown to provide a m ans for securely attarhing the bracltets to the wall or other support. llv pivoting the link 51 to the l"a-;l et U, the fulcrum or center of rotation of the bed is movable with respect to the rzulj.'iu frame '1'. \Vhen the bed in the ve tical position the link hm: moved so that the lull ruin lies at. its position of tlO. st approach to the carrying t am-e. therehv providing a coinpa t strau-ture. With the initial, movement. of the bed from the vertical position the link 3 moves outward. itllflfi'llll," the fulcrum awav from the arrying frame- T. so that the tixed head 11 on the bed frame. clears 'lfhe movem nt oi the lihli 5 is rontroluul hv the pin ll on the lug:- l. operating in eonjnmtion with the cani surface 1:2 which is preferably formed i1itee-ml with the bracket (3. \Vhen the bed is in the vertical position the pin 9 bears against the bottom of the groove ill and the link Steal-st against the standard or guide 14 which carries the cam surface 12. The bed thereby stopped from moving closer to the supporting structure and the foot piece 15 is prevented From contacting W ill and marring: the wall or other supporting structure. The fulcrum 4 is so placed that when the bed is in the vertical posijiion, the center of gravity thereof lies bet-vven the fulcrum and the carrying frame 7. As the bed is moved downward from the vertical position. the pin 9 moving in the groove 13 causes the fulcrum 4 to move out-ward. A further nn'ivement of the bed brings the pin in contact with tl'iejg-irlined cam surface 1?. In passing over this eurlncc the fulcrum is drawn ba kward toward the supporting structure and the friction between the pin and the cam surface 1e luv-reused. This friction new as a partial rounterlialnncc or lirnlie for the descending hvd and prevents it from desu-ndiug too rapidly or from throwir! the right of tin.- nrd agrliii'ist the prr on lowering! it. .is the jlil mam the horizontal position the p'; '9 drops into the 593i? ll} on tho upper end of the steudnrtl ll. locking: the l rd in such poritiorh so that requires considerable upward pull on the foot of the bed to llTlFQflt the pin.

The bed is partly counterlmlnnced in its movement hctwccn the vertical and horizontal positions by Liir coiled springs 17 which are attached at one end t the angle iron 19, extending across the lied at the head and at the other end to the angle 19 which extends transversely between the rackets 6. said angle irons constituting anchoring "means fonthe springs. When the ied 1.: an the on tical position these springs are only in sufii cient tension. to prevent them from rattling and are extended as the bed moves downward. hen the lied is in horizontal position the springs extend in :1 vertical direction between the front. edgcq of the fiiils l8 and 19 to which the two ends; of the springs are, respectivel attached. The line of pnll ofthe springs then licsin front of the pins 9 so that the springs operate LU hold the bed frame in horizontal position. The metallic mattress on the bed frame is preferably attachcd at the head end to the angle '18.

Pivotally attached to the lugs 3 are logs: E21 which are of such length that they Contact with the floor and support the head of the bed when it is in the horizontal position thereby relieving the brackets G and the car-- rying frame of the load. These legs 21 are preferably :ldjustahly attached to the lug 5% so that their position may be varied in order that they ill operate properly to relieve the brackets 6 of the load at the proper time. This feature is important on account of the variable thickness of floor coverings and the varying positions of the brackets 6 above the floor in different installations. These legs are loosely pivoted to the lugs so th at they always maintain a substantially vertical position. Pivotall y attached to the foot piece 15 are legs 20 which also mmntam a substantially vertical position, when the bed is in vertical or horizontal position.

The head frame which is pivoted to the fixed head 11 by the stop hinges 23 is connected at the upper part. with the carrying frame 7 by means; of the spring 24. The spring of such length that it. is slightly in tension. and thereby hoh'h the head frame stationn ry, in either the vertical or horizmr tel positions of the lied. The spring is made of such size and dimensions that it is CHHP. pnrnti'l'eiy rigid under comprcwion and. therefor nct-t as :1 link to push i a: head frame forward or {may from 5h mrrving frame as the bed is moved from either p si tiouv The head Tlrnme i vltlly prover ed from contacting: with the carrying frame as the wl iF moved.
